More than 100 million land mines have been planted just beneath the soil in 90 countries. Land mines are responsible for killing or maiming about 40 to 55 people every day, according to estimates provided by the Red Cross.
There are approximately 500 mine-sniffing dogs deployed worldwide to help detect deadly unexploded land mines so they can be removed safely. The dogs were introduced a decade ago because they have fewer false positives than metal detectors, and they’ve been widely accepted by groups working to remove land mines. But a Belgian-based group, APOPO, has begun employing a new mine hunter that has proven to be much better suited to the work.
